Chris Rankin, who played Percy Weasley, Ron Weasley’s brother and Fudge’s assistant in the series, also tweeted out a message: “BBC news tells me Robert Hardy, the Minister of Magic has died. Terribly sad. He was a very kind man who told wonderful stories. xx”

Hardy’s death was confirmed by his children Emma, Justine and Paul, The Guardian reported Thursday.

“Gruff, elegant, twinkly, and always dignified, he is celebrated by all who knew him and loved him, and everyone who enjoyed his work,” they said in a joint statement.

Among his other famous roles were that of Winston Churchill (on multiple occasions), and as senior vet Siegfried Farnon on the classic British TV series, “All Creatures Great and Small,” based on James Herriot’s beloved novels.

Thank god Daniel Radcliffe is a good kisser, said actress Katie Leung, who admitted she was very nervous about performing the kiss between Cho and Harry. Radcliffe said he was nervous, too, and that "it made it a lot easier," in a behind-the scenes interview. He also described the onscreen smooch as really "fun."

Leung said they dimmed the lights, and she didn't know if that was so the scene would be "less intimidating, or more romantic."

Emma Watson, who plays Hermione Granger, was seriously considering not returning after the fifth "Harry Potter" movie, but she decided to stay because it would be too weird to watch another actress play Hermione in the rest of the movies.

The Ministry of Magic set is the largest in any "Harry Potter" film: It could fit 50 double decker buses. It took 22 weeks to build, but only appears in the film for less than 10 minutes, according to this "Behind the Magic" special.

Imelda Staunton was the only choice to play Dolores Umbridge, who is described as chubby and toad-like in the books and widely hated both by characters and fans.

Stephen King called Umbridge the "greatest make believe villain to come along since Hannibal Lector," according to The Chicago Tribune.

J.K. Rowling was going to have Voldemort (Ralph Fiennes) kill Arthur Weasley (Mark Williams) in order to get Harry into the Department of Mysteries. But, she decided she couldn't go through with killing off such a beloved character (though later she seems to be able to kill off one of Arthur's sons). She said that Arthur might be the only good father in the whole series, and she couldn't bear to kill him.

Another favorite character -- Sirius -- does get killed in the Department of Mysteries by Bellatrix.

Emma Watson said that if she were to play one of the adult characters, she'd pick Professor Severus Snap (Alan Rickman). "I think it'd be cool to play the bad guy," she said in a Moviefone "Unscripted" interview.

Daniel Radcliffe said that filming the fighting scenes in the Room of Requirement "felt like we were in the center of the sun." In the scene, there are a ton of mirrors and there had to be several fire places as well so that a fireplace could be seen in every mirror.

There's a scene where Ron gets flung across the room by Hermione. Actor Rupert Grint said to comingsoon.net that in order to do that stunt, he was set up in a harness attached to a "fat bloke," who then goes up and down a ladder to move him.
